Janis Winehouse to Estranged Daughter Amy: Call Me!

Amy Winehouse's estranged mother, Janis Winehouse, penned an open letter to her daughter, 24, urging her to come home and seek help. She writes:

"We want to help you, but we know that unless you want to be helped, unless you come to us â€" anything we tried would be in vain. So this letter is my way of making sure you know ... that all you have to do is come home to us, Amy, and we'll do everything in our power to get you well again. After all, you are still my baby and you always will be. So just pick up that phone and tell me what's troubling you... Wherever you are, whatever you need, we're here for you day and night."

The full version of Amy's mother's letter was published in the UK's News of the World. It's very nice, heartfelt and, of course, likely to fall upon deaf ears.

The singer has faced some hard times lately. She nixed her tour to support her incarcerated husband, Blake Fielder-Civil, who is being held without bail after allegedly trying to buy off a witness in a pending assault case against him.

Winehouse was recently spotted wandering the streets of London in the middle of the night in just a bra and jeans, looking for her dealer having been asleep.

In a recent statement, Amy Winehouse â€" who nabbed six Grammy nominations in spite of her personal woes â€" apologized to fans for the recent troubles.

"Thank you for all your kind letters and emails," she said. "I am grateful for all your support."
